Improved clinical outcomes in patients with juvenile idiopathic arthritis associated uveitis in the last decade.

Purpose: The purpose of the study was to analyse the development of ocular complications and visual prognosis in juvenile idiopathic arthritis associated uveitis (JIA-uveitis) compared to the previous decade in the light of new treatment guidelines.

Methods: In this retrospective cohort, 143 patients with JIA-uveitis were stratified into two cohorts based on the year of diagnosis of uveitis, <2010 (n = 61) and ≥2010 (n = 82). Development of ocular complications and visual outcomes were analysed by univariate and multivariate methods. Treatment with systemic corticosteroids and immunomodifying medication (IMT) were documented.

Results: In total, 109 and 133 affected eyes, respectively, for cohort 1 (<2010) and cohort 2 (≥2010) were included for analysis. In the multivariate analysis with correction for paired eyes, patients in cohort 1 were at higher risk for cataract surgery (p = 0.03) and secondary glaucoma (p = 5.15 × 10 ). Also, the number of eyes that were legally blind and visually impaired at 5 years of follow-up was significantly higher in cohort 1 (7% versus 2% and 8% versus 0%, p = 0.01 respectively). The number of patients that started IMT was significantly higher in cohort 2 (57% versus 98%, p = 2.17 × 10 ). In cohort 2, both methotrexate and anti-TNF-α therapy were prescribed earlier in the disease course (1.41 versus 0.05 years, p = 8.31 × 10 and 6.07 versus 1.84 years, p = 5.14 × 10 respectively).

Conclusions: The prognosis of JIA-uveitis has improved during the last decade. There is a reduction in the number of cataract surgeries and secondary glaucoma and fewer patients lose their vision parallel with earlier access to tertiary care and earlier introduction of IMT.
